On Coco Gauff's shock win over Venus Williams: I thought she was going to beat Venus Williams. Her parents will be so important for her now and it will be hard knowing who her friends are now, with this new found super stardom. There's a lot more to come from here. she's amazing.

Former British number one on BBC Two
On Coco Gauff's shock win over Venus Williams: What impressed me the most about Coco was her composure, especially playing against one of her greatest idols. She had great court craft great movement around the court and she handled herself amazingly. What an announcement to make on the biggest stage.
As a young player a big win can give you a real springboard and hopefully this win can do that for her. She's got a big, big future ahead.

Dan Evans is in a rich vein of form on grass having won two grass tournaments in the run-up.
And he was a set up against Kyle Edmund at Eastbourne last week, too.

There's huge respect for the fact Dan Evans reached rock bottom and was a bit of a bad boy. But he's fought back in such a short space of time.
He trained with Roger Federer ahead of the clay court season, too, and Dan said he learnt a lot from Roger.
And in many ways Dan is very like Federer as a player. He moves really well and he's got a lovely technique. He's a troublesome opponent for anyone he faces.
*Evans 2-0 Delbonis
It's a flying start for Dan Evans, who breaks Federico Delbonis in the Argentine's opening service game of the match. Looking sharp, the British number three.
Swan v Siegemund

Image source, BBC SportBritish number five Katie Swan has been trying to get her hands on as many tickets as she can for her family and friends to watch her opening match against Germany's Laura Siegemund later - wondering if any of them are bringing the drum?
You may remember Swan brought the instrument to the Fed Cup tie against Kazakhstan in a bid to drown out the noisy visitors.
"I'm really looking forward to playing at Wimbledon again - it is my favourite time of the year, playing at home and on the grass," she told BBC Sport's Betty Glover at the pre-tournament WTA Summer Party in Knightsbridge.
"It's really special because only happens during this time of the year and I have my family and friends here so I get to see them and they can support me.
"I try to get as many of friends to come as I can - but so many want to come! I've got my mum and my brother coming over from the States to be with me."

Walking to Court 18 for Dan Evans’ match, I got caught up among a mass of photographers, all clearly waiting for someone.
And look who walked down the stairs! The Duchess of Cambridge is here today, she’s watching Britain’s Harriet Dart first up!

On Court 14, Harriet Dart has a royal visitor - Catherine, Duchess of Cambridge!
Kate is sitting between GB Fed Cup captain Anne Keothavong and British player Katie Boulter.
No pressure then.

Among the Brits in action from the off on day two at Wimbledon is Harriet Dart, who has just got her opening match against American Christina McHale under way on court 14.
The 22-year-old world number 182 will be hoping to improve on her first-round exit last year.

Kyrgios v Thompson
Image source, ReutersIt's been a stuttering and typically stormy 2019 for Nick Kyrgios so far, where asides from arguing with officials and staying up until 3am in the morning playing Fifa he has struggled to get going in the Grand Slams.
The Australian fell to Milos Raonic in straight sets in the first round at the Australian Open and then missed Roland Garros due to illness.
He faces countryman Jordan Thompson today, with just one place in the standings separating the pair - in fact, if Thompson wins he is guaranteed to move ahead of Kyrgios when the new rankings are released on Monday, 15 July.

Philip West: Lots of excellent match-ups in prospect today, but it’ll be particularly interesting to see how Nick Kyrgios, Serena Williams, and Johanna Konta get on. Querrey v Thiem is an interesting match, too!
Meanwhile Australian queen bee Ashleigh Barty is making her own entrance.
I'm getting volleyball-scene-in-Top-Gun vibes.

Image source, BBC SportWalking past Centre Court, Pry, Rajan and Lloyd caught my eye - they have really dressed the part!
Rajan lives in Perth, Australia, but is back in the UK as he's just become an uncle twice over - both his sister and his sister-in-law have given birth recently, so congratulations to them!
I asked them what the best thing about Wimbledon was, and they had only one answer: "Roger Federer". Thankfully, they have got tickets for Centre Court today.
Lloyd added: "Wimbledon is Glastonbury for people who didn't get in!"
Still a bit of bitterness about not getting a ticket, I sense...
Highlights: Upset as Yulia Putinseva beats world number two Naomi Osaka
Over in the women's draw, Naomi Osaka continued her underwhelming form at Wimbledon.
She has not been beyond the third round in three previous campaigns in SW19.
And she was on the point of tears at times in the aftermath of her 7-6 (7-4) 6-2 defeat by Yulia Putintseva of Kazakhstan.
"There are answers to questions that you guys ask that I still haven't figured out yet," said the 21-year-old.
"I wouldn't blame my age on anything. I've done a lot of good things. I've done a lot of bad things. But I'm not the type of person that would say because I'm young I can get away with doing certain things."
Andy Murray column

If you didn't know, Andy Murray quite likes art. And if you did know that, you probably follow his Instagram account...
So, in his latest BBC Sport column, he tells us how the time out with his hip injury helped him appreciate art - and led to an attempt at painting...
"I was trying to flick the paint and use all sorts of techniques but I was getting it on the ceiling, everywhere. It was a disaster!" he laughed.

Stefanos Tsitsipas - the 20-year-old Greek sensation - waved goodbye to Wimbledon after a four-set defeat by Jiri Vesely, ranked 118 places behind him.
"When you get so much support, so much energy, so much positivity from everyone, and just ruin everything by yourself, it's devastating," he said.
Alexander Zverev, the 22-year-old German, came a cropper against unheralded Italian Thomas Fabbiano.
He was equally scathing in his self-assessment.
"I get down on myself a lot. Everything that happens outside the court affects you. The last two days, I would say, are very rough for me personally. I'm not going to get into details," he added.
